Thermodynamics of solvation for methylproline peptides

Biopolymers, 1983
AbstractWe have determined thermodynamic parameters for transfer of N‐acetyl,N′‐methylamide derivatives of proline and methylprolines from carbon tetrachloride and from chloroform to water. The hydrophilic nature of the diamide model peptides is demonstrated by the negative free energies and enthalpies for transfer.

The statistical thermodynamics of solvation

Theoretical and Experimental Chemistry, 1970
Statistical mechanics provides the basis for a rigorous theory of molecules and molecular complexes in chemically inert media. It is found that the free energy of solvation may be calculated, provided the distribution function for the solvent molecules around the solute molecules is known.

Structural thermodynamics of protein preferential solvation: Osmolyte solvation of proteins, aminoacids, and peptides

Proteins: Structure, Function, and Bioinformatics, 2008
AbstractProtein stability and solubility depend strongly on the presence of osmolytes, because of the protein preference to be solvated by either water or osmolyte. It has traditionally been assumed that only this relative preference can be measured, and that the individual solvation contributions of water and osmolyte are inaccessible.

Solvation thermodynamics

2006
Abstract The study of solvation thermodynamics has a very long history. Almost any experiment carried out in a solution necessarily involves solvation. Prior to the 1970s there were several quantities referred to as standard Gibbs energies of solution (or hydration, when the solvent is water).

Solvation Thermodynamics and Non-Randomness. Part I: Self-Solvation

Journal of Chemical & Engineering Data, 2010
The central theme in this series of papers is the development of a coherent and consistent equation-of-state model of fluids in the frame of solvation thermodynamics. Two main ingredients will be used for this purpose: the first will be the successful conductor-like screening model (COSMO) type group-contribution models with their quantum-mechanical ...

Nonlinear effects in dipole solvation. I. Thermodynamics

The Journal of Chemical Physics, 1997
The method of Padé truncation of perturbation expansions for thermodynamic potentials of molecular liquids is extended to the calculation of the solvation chemical potential of an infinitely dilute dipolar solute in a dipolar liquid. The Padé form is constructed to include nonlinear solvation effects of dipolar saturation at large and the linear ...

Solvation Thermodynamics of Biopolymers

1993
For any biochemical process taking place in aqueous medium one can view the Gibbs energy change (or any other thermodynamic quantity) as comprising two contributions: one originating from the solutes involved in the process, and the second including all possible solvent effects. Thus, we write $$\Delta {G^\ell } = \Delta {G^g} + \delta G$$ (14.1)

Solid Solvates of C60 Compositions and Thermodynamics

Journal of Thermal Analysis and Calorimetry, 1999
Compositions of the solid solvates of C60 with 1,2-dichlorobenzene and 1,3,5-trimethylbenzene were determined with the help of experimental procedures developed. Possible correlations between compositions and thermodynamic properties were discussed.

Multiparameter Correlations for Description of Thermodynamic Parameters of Solvation: I. Enthalpy of Nonspecific Solvation

Russian Journal of General Chemistry, 2002
Applicability of a linear solvation-energy approach for descripition of the solvation enthalpies of nonelectrolytes is examined. In most cases a good fit of experimental solvation enthalpies can be attained. However, the resulting data are difficult to interpret in terms of different types of intermolecular interactions.
